Struct DataAvailableStream 

pub struct DataAvailableStream<T: DdsType + Send + Sync + 'static> { /* private fields */ }

Stream of “data available” events. Yields () every time there are new samples in the reader. Does not consume samples — the caller must call take() or take_stream separately.

Trait Implementations

impl<T: DdsType + Send + Sync + 'static> Stream for DataAvailableStream<T>

type Item = ()

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Option<()>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
